moden aos skeletons are larger than 7e skittles, but the proportiins are such that their hands & skulls are still smaller than old tomb kings skeletons.
This conversion w empire state troops should still work, but would be a bit more difficult due to the weapon & shield arms maybe not all being separate bits? Not sure, I haven't seen the most recent recut sprue, but uou might have some trouble separating out some of the hands, weapons, & shields to transplant over. Should still be do-able regardless, and will look better than the same conversion but w tomb king skeletond, but just a bit trickier than with the old 7e vamp count skittles.
